<p>A tear portion is formed at a substantially center portion in a longitudinal direction and at both end portions in a lateral direction of an air bag door portion of an instrument panel so as to be formed in an H shape in a plan view. In the air bag door portion, protrusions are protruded downward at positions at both sides in a longitudinal direction of an automotive vehicle having therebetween a center portion of the tear portion, these protrusions being integrally formed with the air bag door portion. Accordingly, it is structured such that during expansion of the air bag body, the expanding air bag body abuts lower surfaces of the protrusions, so as to press the protrusions upward. Therefore, even in a case wherein the air bag door portion and the main body portion of the trim member for the automotive vehicle are formed of the same resin, a quality of an outer appearance is not deteriorated, and a break force of a break portion of the air bag door portion is reduced to a desired value.</p> |
